Is it normal to never fart?
Depends.It depends
It’s common not to notice yourself farting much, but everyone produces some gas, and most people pass it now and then. If you truly can’t pass gas at all—especially with pain or a swollen belly—get medical advice.
Lots of gas escapes quietly, and some people produce less depending on what they eat, so you may simply not notice it. But literally never passing gas would be unusual; most people do it occasionally, even if they’d rather not announce it.
If you mean you can’t pass gas at all and you also have significant belly pain, swelling, or vomiting, get medical advice promptly. Otherwise, not noticing any is usually nothing to worry about.
